Hydrokinetic power transmission system with a substantially
ideal functional relationship between
output speed and tractive effort

ABSTRACT

THIS SPECIFICATION DESCRIBES A HYDROKINETIC TORQUE CONVERTER TRANSMISSION HAVING AN INCREASED LOW SPEED TORQUERATIO IN GEARED PORTIONS OF THE MECHANISM AND HAVING A BLADED STATOR OF VARIABLE GEOMETRY IN THE TORQUE CONVERTOR PORTION OF THE MECHANISM. THE INDIVIDUAL STATOR BLADES ARE MOUNTED ON ROTATABLE STATOR BLADE SHAFTS WHICH CAN BE ROTATED TO EFFECT ANGULAR ADJUSTMENT OF THE STATOR BLADES BY MEANS OF A RACK-AND-PINION SERVO. AN INCREASED DEGREE OF DEFLECTION OF THE TOROIDAL FLUID FLOW IN THE STATOR REGION OF THE CIRCUIT IS OBTAINED AS THE CONVERTER SPEED RATIO INCREASES THEREBY PROVIDING A OVERALL TORQUE RATIO CHARACTERISTIC THAT APPROACHES A THEORETICAL, IDEAL PERFORMANCE.

PUBLISHED MAY 4, 1971 Int. Cl. F1611 47/00 US. Cl. 74-732 4 Sheets Drawing. 13 Pages Specification MIPI/f i I K 35 This specification describes a hydrokinetic torque converter transmission having an increased low speed torqueratio in geared portions of the mechanism and having a bladed stator of variable geometry in the torque convertor portion of the mechanism. The individual stator blades are mounted on rotatable stator blade shafts which can be rotated to eifect angular adjustment of the stator blades by means of a rack-and-pinion servo. An increased degree of deflection of the toroidal fluid flow in the stator region of the circuit is obtained as the converter speed ratio increases thereby providing an overall torque ratio characteristic that approaches a theoretical, ideal performance.
